Safety Device for Power Window - A safety device for power window, which generates pulses by rotation of a raising/lowering motor for raising or lowering a window glass of a power window for vehicle, and determines occurrence of pinching of a foreign substance from change in pulse width during closing operation of a window, and thus reverses window operation into window opening operation, is obtained, wherein false determination due to variation in voltage of a battery hardly occurs.

CARRIER FOR REPLENISHMENT, DEVELOPER FOR REPLENISHMENT, DEVELOPER CARTRIDGE FOR REPLENISHMENT, AND IMAGE FORMING APPARATUS - The present invention provides a carrier for replenishment including an associated particle in which single particles each having a core material and a resin layer covering the core material, are bound via the resin layer, the carrier being used in a developer for replenishment of a trickle development system, and the system including performing development while the developer for replenishment is replenished, upon development of a latent image on a latent image holding member using a development unit.

NON-VOLATILE SEMICONDUCTOR MEMORY DEVICE - According to one embodiment, a non-volatile semiconductor memory device includes a writing unit that performs a writing operation on memory cells while stepping up a writing voltage based on a check result of a verifying operation on the memory cells, a threshold-value determining unit that determines threshold values of the memory cells based on a write verifying operation on the memory cells, and a step-up voltage changing unit that changes a step-up voltage for stepping up the writing voltage, based on the threshold values of the memory cells.

MAGENTA TONER, DEVELOPER, TONER CARTRIDGE, PROCESS CARTRIDGE, IMAGE FORMING APPARATUS, AND IMAGE FORMING METHOD - A magenta toner including toner particles containing a colorant and a binder resin is provided. The colorant contains C.I. Pigment Red 122 and C.I. Pigment Yellow 180 and a mass ratio of the C.I. Pigment Red 122 and the C.I. Pigment Yellow 180 is in the range of 99:1 to 10000:1. The binder resin contains a polyester resin and a polyester resin having a repeating unit obtained from a Bisphenol A alkylene oxide adduct expressed by the following chemical formula is used as the polyester resin:

SEMICONDUCTOR DEVICE AND TRIMMING METHOD FOR THE SAME - According to one embodiment, a semiconductor device includes a termination circuit and a controller. The termination circuit includes a first resistor connected to an external connection terminal, a plurality of first transistors of a first conductive type connected in parallel between the first resistor and a voltage source, a second resistor connected to the external connection terminal, and a plurality of second transistors of a second conductive type connected in parallel between the second resistor and ground. The controller is configured to control switching of the first and second transistors such that a combined resistance value of the first and second resistors and the termination circuit is constant.
